SALL2 and cancer: SALL2/Sall2 is involved in the proper closure of the neural tube and the optic fissure [10, 11], morphological differentiation of hippocampal neurons [12], stemness maintenance of conjunctival epithelial stem cells [13], inhibition of DNA synthesis and entry into quiescence [14], promotion of cell death under genotoxic stimuli [15–17], and cell migration of cancer cells and embryonic fibroblasts [7–19].
